So far, the blaze has burned over 2,600 hectares (10 square miles) and continues to grow.

"The fire conditions are extreme," Darby Allen, regional fire chief for the Regional Municipality of Wood Buffalo, said during an 11 a.m. update Tuesday.

"The humidity levels are going to be decreased quicker because the ambient temperature is hotter, so that means the fire will be able to go more ferociously and quicker than in days previously," Allen added.

The smoke from the wildfire has also created poor air quality across the region. People with respiratory issues should stay alert and minimize their exposure to the smoky air.
